Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a medium for forced insertion of a voice instruction in a flat shunting system.
Background
The railway flat shunting system comprises a plurality of flat-shunting wireless devices, wherein the flat-shunting wireless devices can be specifically flat-shunting hand stations, machine controllers and district platforms. The leveling wireless devices in the same railway flat shunting system typically operate in a pass-through mode, i.e., at one radio frequency. When the flat-tone wireless device M in the system performs voice communication by using the same radio frequency, when the flat-tone wireless device M in the system occupies a forward channel for voice communication (at this time, other flat-tone wireless devices in the system can receive voice information sent by the device M), if the flat-tone wireless device N wants to forcibly occupy the forward channel (for example, in a more emergency situation) for voice communication, the device N needs to send a forcible signaling to the device M through a reverse channel to terminate the forward channel occupied by the device M, so that the device N obtains the right to use the forward channel.
In the prior art, in a railway flat shunting system, two groups of time slots are divided on a time axis on a communication channel constructed by a radio frequency (for example, 12.5 Khz). Fig. 1 shows a time slot distribution diagram provided by an embodiment of the present application, as shown in fig. 1, which includes 2 groups of time slots on a time axis, and each group of time slots includes 6 time slots. Specifically, the time slot group 1 includes a time slot a, a time slot B, a time slot C, a time slot D, a time slot E, and a time slot F; slot group 2 includes slot a ', slot B', slot C ', slot D', slot E ', and slot F'.
As shown in fig. 1, one of the time slots (e.g., time slot set 1) is used as a forward channel for voice data transmission; another set of slots (e.g., slot set 2) is used as a reverse channel for sending the strong signaling. For example, device M may send voice data to other flat-tone wireless devices in slot a, slot B, slot C, slot D, slot E, slot F; in the timeslot a ', the timeslot B', the timeslot C ', the timeslot D', the timeslot E ', and the timeslot F', the device N may send a break-in signaling to the device M. If the device M receives the forced insertion signaling in any one of the time slots in the time slot group 2, the device M stops occupying the forward channel, so that the device N obtains the use right of the forward channel, and at this time, the device N can perform voice communication with other flat wireless devices. The method has the defects that the radio frequency can only be used by one railway flat shunting system, and the two railway flat shunting systems can not share one radio frequency for voice communication so as to finish the application scene of shunting operation.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
The railway flat shunting system comprises a plurality of flat-adjustment wireless devices, wherein the flat-adjustment wireless devices can be specifically flat-adjustment hand tables, machine controllers and district tables. (for example, in a railway flat shunting system, there are 10 flat shunting stations, 1 mechanical controller and 1 district station, and there are 12 flat shunting wireless devices, the mechanical controller is arranged in the railway flat shunting system, the flat shunting stations are used for the personnel in the air shunting, and the district station is arranged in the signal building of the railway station and is used for commanding the operation).
The flat-tone wireless devices in the same railway flat-shunting system generally operate in a pass-through mode, i.e., at a radio frequency. When the flat-tone wireless device M in the system performs voice communication by using the same radio frequency, when the flat-tone wireless device M in the system occupies a forward channel for voice communication (at this time, other flat-tone wireless devices in the system can receive voice information sent by the device M), if the flat-tone wireless device N wants to forcibly occupy (for example, there is more urgent signaling or conversation) the forward channel for voice communication, the device N needs to send a forcible signaling to the device M through a reverse channel to terminate the occupation of the forward channel by the device M, so that the device N obtains the right to use the forward channel.
In the prior art, in a railway flat shunting system, a TDMA (Time division multiple access) communication mode is adopted to realize wireless transmission of voice data. On a communication channel constructed at a radio frequency (e.g., 12.5 Khz), two sets of time slots are divided on a time axis. As shown in fig. 1, 2 groups of slots are included on a time axis, and each group of slots includes 6 slots. Specifically, the time slot group 1 includes a time slot a, a time slot B, a time slot C, a time slot D, a time slot E, and a time slot F; slot group 2 includes slot a ', slot B', slot C ', slot D', slot E ', and slot F'.
As shown in fig. 1, a reverse channel may be defined into one of the sets of slots (e.g., slot set 2). Specifically, slot group 1 is used as a forward channel for voice data transmission; slot group 2 is used as a reverse channel for sending the strong insertion signaling. For example, the calling device M may send voice data to other flat-tone wireless devices in time slot a, time slot B, time slot C, time slot D, time slot E, and time slot F; in the time slot a ', the time slot B', the time slot C ', the time slot D', the time slot E 'and the time slot F', the called device N may send the break-in signaling to the calling device M. If the calling device M receives the break-in signaling in any time slot in the time slot group 2, the calling device M stops occupying the forward channel, so that the called device N obtains the right of use of the forward channel, and at this time, the called device N is used as a new calling device to perform voice communication with other flat wireless devices. The method has the defects that the radio frequency can only be used by one railway flat shunting system, and the application scene that two railway flat shunting systems share one radio frequency to finish shunting operation cannot be realized.
Further, fig. 2 shows a second timeslot distribution diagram provided in the embodiment of the present application, as shown in fig. 2, if one timeslot (for example, timeslot F) in timeslot group 1 (described by taking timeslot group 1 as an example) is used as a reverse channel, a strong insertion signaling is received; the other slots (slot a, slot B, slot C, slot D, slot E) are used as forward channels. Thus, although the time slot group 2 is saved, and the two railway flat shunting systems share one radio frequency to complete shunting operation, when voice data is transmitted, each time slot corresponds to a voice frame to be transmitted, and when one time slot F is occupied to be used as a reverse channel, the transmitted voice data is lost, and the transmission quality of the voice data is influenced.
And, currently, in order to reduce the transmission loss of voice data, a method of developing a reverse channel once every several slot groups may be employed. Specifically, fig. 3 shows a third timeslot distribution diagram provided in the embodiment of the present application, as shown in fig. 3, a reverse channel F3 is developed for three consecutive timeslot groups 1, and all of the timeslots A1, B1, C1, D1, E1, F1, A2, B2, C2, D2, E2, F2, A3, B3, C3, D3, and E3 in the three timeslot groups 1 are used as a forward channel. However, in this method, since the duration of each timeslot group is 360ms, that is, when the device N wants to perform communication break-in and break-off the communication of the device M, the device N needs 360 × 3=1080ms to send the break-in signaling to the device M through the reverse channel F3. In the flat shunting operation, shunting signaling or voice data is generally transmitted and received in a locomotive moving state. The response speed of the signaling is required to be fast, and the delay time of 1080ms is too long for the use environment of the shunting operation. If the transmission fails, the reissue operation can be realized after 1080ms, and potential safety hazards exist in the shunting operation.
In view of the above problems, embodiments of the present application provide a method, an apparatus, a device, and a medium for break-in of a voice command in a flat shunting system, so as to implement that two railway flat shunting systems share one radio frequency for voice communication, so as to complete an application scenario of shunting operation, and improve transmission efficiency of a communication data frame used as a reverse channel in a timeslot, thereby improving response speed and a sending success rate of a shunting signaling in a break-in state, and ensuring timeliness of transmission of the break-in signaling. The following is described by way of example.
The first embodiment is as follows:
to facilitate understanding of the present embodiment, a detailed description will be given to a method for inserting a voice command in a flat shunting system disclosed in the embodiments of the present application. Fig. 4 is a flowchart illustrating a method for enforcing voice commands in a flat shunting system according to an embodiment of the present application, in which each flat-tuned wireless device in the flat shunting system communicates within a communication channel constructed by a target radio frequency; the method is applied to a calling device in a flat-tone wireless device; the calling equipment is the flat-tone wireless equipment which is currently used by the first user for voice communication in the flat-tone wireless equipment; other leveling wireless devices except the calling device in the leveling wireless devices are called devices; for each first time slot group on the communication channel, using the communication channel for a reverse channel in a designated part of designated time slots in the first time slot group, and using the communication channel for a forward channel in other time slots except the designated part of the designated time slots in the first time slot group; any two adjacent time slots in the same first time slot group are separated by 1 time slot in the second time slot group. As shown in fig. 4, the method comprises the following steps S401 to S402:
s401: responding to a voice communication operation of the first user so as to transmit a first voice instruction to each called device through a forward channel in other time slots except for the specified partial time slot; the first voice instruction carries a current time slot identifier and first voice communication content corresponding to the voice communication operation; the called device is used for playing the first voice communication content and synchronizing the time slot of the called device according to the current time slot identifier.
In this embodiment, the flat shunting system may specifically be a railway flat shunting system. The flat shunting system comprises a plurality of flat shunting wireless devices. Since all the flat-tone wireless devices communicate in the communication channel constructed by the target radio frequency, when one of the flat-tone wireless devices (i.e., the calling device) is being used by the first user to occupy the communication channel for voice communication, the other flat-tone wireless devices (i.e., the called device) can only hear the first voice communication content sent by the first user using the calling device, and at this time, the called device cannot communicate while the calling device occupies the communication channel for voice communication.
In this example, any one of the flat-tuned wireless devices in the flat-tuning system can be used as the calling device, and as long as the flat-tuned wireless device occupies the communication channel for voice communication, the flat-tuned wireless device is used as the calling device, and the other flat-tuned wireless devices are used as the called devices.
Fig. 5 shows a fourth slot profile provided in an embodiment of the present application, as shown in fig. 5, in this embodiment, a communication channel includes a plurality of first slot groups (the first slot groups include a slot a, a slot B, a slot C, a slot D, a slot E, and a slot F) and a plurality of second slot groups (the second slot groups include a slot a ', a slot B', a slot C ', a slot D', a slot E ', and a slot F'), where any two slots in each first slot group are separated by a slot in 1 second slot group, and any two slots in each second slot group are separated by a slot in 1 first slot group.
In one possible embodiment, each first slot group includes 6 slots, and each slot in the first slot group is 30ms. Each second slot group also includes 6 slots, and each slot in the second slot group is also 30ms. As shown in fig. 5, since any two slots in each first slot group are spaced apart by slots in 1 second slot group, the total slot of each first slot group is actually 360ms (6 × 2 × 30 ms). Similarly, the total time slot of each second time slot group is also 360ms in practice.
As shown in fig. 5, for each first group of time slots on the communication channel, the communication channel is used for the reverse channel in a designated portion of the designated time slots within the first group of time slots. The designated time slot in the first time slot group may specifically be the last time slot (i.e., time slot F) in the first time slot group, and the designated partial time slot is a partial time slot corresponding to a middle part of the three partial time slots, which is obtained by equally dividing the designated time slot into three partial time slots, so that when the designated time slot F is 30ms, the designated partial time slot is 10ms.
On a communication channel, the communication channel is used as a reverse channel in a designated part of the time slots, and the communication channel is used as a forward channel in the time slots other than the designated part of the time slots.
In this embodiment, when the first user uses the calling device to perform voice communication, the calling device first performs a voice communication operation, for example, the first user continuously presses a target button on the calling device and performs voice communication. The calling device is responsive to the voice communication operation of the first user to cause the calling device to transmit a first voice instruction to each of the called devices over the forward channel in time slots other than the designated partial time slot. The first voice instruction carries a current time slot identifier and first voice communication content corresponding to the voice communication operation. The first voice instruction is specifically a voice shunting instruction and is used for dispatching vehicles.
And aiming at any one called device, after the called device receives the first voice command, playing the first voice communication content, and synchronizing the time slot of the called device according to the current time slot identifier. In this embodiment, since the called device can only send the break-in signaling to the calling device through the reverse channel, the purpose of synchronizing the time slot of the called device according to the current time slot identifier is to calculate when the break-in signaling can be sent to the calling device.
S402: in the process of using the calling device to carry out voice communication by the first user, when a forced insertion signaling sent by any called device is received through a reverse channel in a specified part of time slots, the occupation of a forward channel is stopped to send a first voice instruction, so that the called device responds to the voice communication operation of the second user, and the occupation of the forward channel sends a second voice instruction to other flat wireless devices except the called device.
In the process of using the calling device to perform voice communication by the first user, if one of the called devices needs to urgently occupy the forward channel to send a second voice instruction to other flat wireless devices except the called device, the called device can send a break-in signaling to the calling device through a reverse channel in a specified part of time slots. When the calling equipment receives the break-in signaling sent by any called equipment, the calling equipment stops occupying the forward channel to send the first voice instruction, so that the called equipment as new calling equipment acquires the use right of the forward channel. The second voice instruction carries second voice communication content corresponding to the voice communication operation of the second user and a current time slot identifier. The second voice command also belongs to a voice shunting command and is used for dispatching vehicles.
In this embodiment, since in the same first time slot group, the communication channel may be used as both a forward channel for transmitting the first voice command and a reverse channel for receiving the forced signaling transmitted by the called device. Thus, the second time slot group can be saved, and other flat shunting systems can use the second time slot group for voice communication to finish shunting operation. And then, the two railway flat shunting systems can share one target radio frequency to carry out voice communication so as to finish the application scene of shunting operation.
Also, by using a designated portion of the timeslots in each first timeslot group for the reverse channel in this embodiment, the method is advantageous for reducing the transmission loss of voice data compared to using a complete timeslot in the first timeslot group for the reverse channel. Meanwhile, in the embodiment, by adopting the designated part of the time slots in each first time slot group to be used for the reverse channel, compared with the method of developing the reverse channel once by adopting a plurality of time slot groups, the method is favorable for improving the transmission efficiency of the communication data frame used as the reverse channel in the time slot, thereby improving the response speed and the sending success rate of the shunting signaling in the strong insertion state and ensuring the timeliness of the transmission of the strong insertion signaling.
